Goldenrivet,
The morse code you hear when a message is received is a number group interspersed with spaces. The only letter in this group from memory is the last character which is a G.
Next time I hear it I can write it down and post it here.
(1) It is definately NOT Bernard lol!
(2) It is nothing that makes sense.
I suppose it is a simulation of an Enigma message.
By the way the morse code is not that fast for anyone used to using this mode of communications as I was (Merchant Marine Radio) for many years in the past.
Unfortunately now CW or Morse is seldom used, having been superseded by things like teleprinter and satellite communications.
However at the end of the day a morse code signal will get through where nothing else will under poor atmospheric conditions..
Hope this is of help to you.
